Abstract
A thermal eraser for erasing tactile drawing features from a tactile drawing medium, along with methods of erasing tactile drawing features formed on a tactile drawing medium, are disclosed. The thermal eraser has a heated tip that can be heated to a temperature sufficient to cause the tactile drawing feature to flow back into the surface of the tactile drawing medium. The heated tip has a tip temperature that can be controlled by a temperature-regulating circuit. A set-point temperature can be used to set the tip temperature and maintain the tip temperature. The thermal eraser can be controlled by hand or by an electro-mechanical device such as a tactile printer.
